This little known chart is the Fed's attempt to anticipate a recession in the US economy. The reading from last November is only 3.84%, but that is higher than all but 3 months when a recession did not immediately proceed.

Even the Fed, which has for years been describing the economy as "expanding at a moderate pace," and which a few months back was saying it was "hawkish," has, through Janet Yellen's testimony today, been forced to admit that a rate cut may again be on the horizon.
